Abstract
508,012. Deoxidizing steel. ROCHLING'SCHE EISEN UND STAHLWERKE GES. Dec. 20, 1937, No. 35195. Convention date, Dec. 28, 1936. [Class 72] In the deoxidation of steel baths with calcium carbide, the melting point of the calcium carbide and its reaction products is reduced to below the melting point of the steel by the addition of one or more of the fluorides of alkali and alkaline earth metals and aluminium, the carbide content of the mixture used being at least 50 per cent. Oxides and carbonates of alkali and alkaline earth metals and aluminium in an amount up to 10 per cent may be added to the carbide mixture especially when the latter contains fluorspar and cryolite. Specifications 1947/02, 18962/09, [both in Class 72], and 395,158 are referred to.
